Will.i.am & Jessie J Have 'Uncomfortable' Bust-Up On 'The Voice'

True colours showing?

Will.i.am and Jessie J reportedly had an "uncomfortable" bust-up on their new talent show The Voice.

The pair are said to have gotten into a heated argument over a contestant in a yet-to-be aired episode of the BBC show. Insiders say they are refusing to speak to each other and have barely made contact since.

"There was one point where my team came in and expressed concerns on the banter between the coaches," Will admitted to the Mirror.

"I am the most unconfrontational man in the world – it is not my style – but that was the first time they have ever seen that side of me and they were like, ‘Will, what are you doing?’"

Apparently, the former Black Eyed Peas frontman was warned to change his behaviour as he was becoming to aggressive.

"They pulled me back in the dressing room and told me that I should not be doing that. They said it certainly didn’t look like banter." During the argument, Jessie reportedly mocked Will, saying: "I’m William and I’ve got two dashes in my name."
